2Workingprinciple andDiagram ofthe instrument

2.1 Workingprinciple

An impact bodywith a sphericaltest tip madeof

tungsten carbide ispropelled against thesample

surface by aspring force andthen rebounds back.

At adistance of 1mmfrom the samplesurface, the

impact and rebound velocity ofthe impact body,

when passing through the coilin its coilerholder,

induces in thecoil and electricvoltage proportional

to the velocities fo themagnet. Leeb hardness as the

follo wing formula:
